Snes9x bad checksum4/18/2024 ![]() I have updated everything, have tried many types of roms and changed video settings all to no avail. i keep getting a 'bad checksum error' in snes9x Started by uselessearthboundfan, January 09, 2023, 05:45:43 PM Previous topic - Next topic Print Go Down Pages 1 uselessearthboundfan Newbie Posts: 1 Logged January 09, 2023, 05:45:43 PM so recently, I decided I would try out an earthbound Romack that Romack being the 'earthbound enhanced' rom.

The original mario world works, but not this one. ![]() It says bad checksum, and then goes into a black screen. I downloaded 'Kaizo Kindergarten' By pangaeapanga, but for some reason, it doesn't work. : Redirecting save state to "/home/pi/RetroPie/roms/snes/Super Mario World (USAyyy).state". I have been a Nintendo fan for years, and I decided to try to play a rom hack on my computer. : Redirecting save file to "/home/pi/RetroPie/roms/snes/Super Mario World (USAyyy).srm". : Remap directory: "/opt/retropie/configs/snes/".

There are a couple things going on but first here is my info: What if a fixed checksum in one game means track number 42 won't play in the 30th hour of gameplay in whatever RPG it might be?Īny other insights into checksum errors, what it means, and whether they need fixed? I was going through Genesis games, but I also did a few SNES ones last night.Hey, all! I'm fairly new to retropie so please bear with me but I am having trouble getting any ROMs to start successfully. So luckily I had a copy of that entire folder somewhere else and reverted to before I started fixing checksum errors.Īny other insights into checksum errors, what it means, and whether they need fixed? I was going through Genesis games, but I also did a few SNES ones last night. ![]() I realized, maybe I shouldn't be doing this? Maybe there's absolutely no need to do this and that in some cases it might mess stuff up. I found another folder with the same rom before the checksum fix and the music worked. While I got Hyper Metroid to work, I am having trouble getting the infamous Justin Bailey hack to work. Check the hack page and you'll see the creator will usually specify a rom type (headered or unheadered) Typically for hacks I use the Japanese unheadered rom and rarely have problems. I get most of the way through, then I notice there's a rom whose intro music was just garbled noise after the checksum correction. You've got a mismatch between the rom the hack was built with and the rom you're patching the hack to. So I spent about an hour going through my curated folder, looking for checksum errors when booting in an emulator, fixing them with the tool, then testing again to see if fixed. ![]() So I found a tool that fixes checksums, which I just assumed should be cleaned up, why not? Might help games run when they might otherwise not. ![]()
